Arthur was educated at Hertford College, Oxford and qualified B.A. in 1908 and M.A., M.B., M.R.C.S., and L.R.C.P. in 1911. He was then employed at St Thomas Hospital as House Physician, Obstetric Physician and Casualty Officer, as well as being the Resident M.D. at Queen Charlotte's Hospital. When war broke out, Arthur joined the British Red Cross Society in France, arriving in October 1914, and was attached to No 2 Motor Ambulance Convoy, and No 5 Hospital. In 1915, he joined the R.A.M.C. under the rank of temporary Lieutenant, he worked at Netley, and then joined No 4 and No 2 General Hospitals in France. Arthur died of broncho-pneumonia, after being admitted as a patient in No 2 General Hospital. A brother-officer wrote - "It is a year since i personally saw him last, but he still stands out to me, as he will to so many others, as the best, the most lovable, and the pluckiest of all our band..... If you could have seen him, say at 3 a.m., at that dreadful shambles, the No 5 Hospital, his spirit quite unbroken and his sympathy and his gaiety undimmed, you would know what I mean." Another wrote - "All who knew him loved him. Others will tell you of his work in the hospital, and of the unbounded affection in which the patients held him. To me he stood for the ideal of a Christian gentleman. Easily the most popular Officer on the Staff... One knew and felt that with him religion was intense reality. The influence of his life will never be lost." Another stated "He was loved by everyone" and described him as "quite young, he had most wonderful tact, a good doctor, keen, unselfish, always cheery, and adored by his patients. Also he was a 'Sahib' in the true sense of the word." Arthur was the only son of Sir Thomas Frederick Chavasse, M.D., C.M., F.R.C.S. and Lady Frances H Chavasse of The Linthurst Hill, Barnt Green, Worcestershire.
